我已将我的ASP.NET站点上传到托管服务器。 虽然我使用了visual studio的比较器 - 没有错误。
现在，当代码尝试访问该类时，我收到以下错误：
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS0246: The type or namespace name 'vSQL' could not be found (are you missing a using directive or an assembly reference?)
Source Error:
Line 32:
Line 33: string checkActivity = "SELECT Count(*) FROM activity WHERE activityCode=" + activityID.Text + ";";
Line 34: vSQL checkSqlActivitys = new vSQL();
Line 35: DataSet ds = new DataSet();
Line 36: ds = checkSqlActivitys.sqlRet(x, checkActivity);
我需要更改/添加什么？
